Question
After an infant underwent a detailed ultrasound examination of the hip joint four days prior, a polio vaccine was administered. The next day, blood strands were found in the infant’s stool. In this situation, does the vaccine administration affect the infant’s growth, and what possible side effects might occur?
Answer
Generally, administering the polio vaccine to an infant after an ultrasound examination does not have a direct impact on the infant’s growth. Regarding the occurrence of blood strands in the stool, it may be due to slight injury to the intestinal wall during the ultrasound examination. It is advised not to worry excessively and to closely monitor the situation. If the condition persists, seek medical attention promptly. Typically, an ultrasound examination does not interfere with an infant’s growth. I hope these suggestions are helpful to you, and wish you good health!
